Part of endosperm is liquid in

Options

A. Coconut
B. Datura
C. Passiflora
D. Ricinus.

Answer

**Step-by-Step Solution:**

1. **Understanding Endosperm:** The endosperm is a tissue that provides nutrition to the developing embryo in seeds. It can develop in different forms based on the method of cell division.

2. **Types of Endosperm Development:**
- **Free Nuclear Endosperm:** In this type, the primary endosperm cell undergoes karyokinesis (nuclear division) without cytokinesis (cell division), leading to multiple nuclei in a shared cytoplasm. This results in a liquid endosperm.
- **Cellular Endosperm:** Here, the primary endosperm cell undergoes both karyokinesis and cytokinesis, resulting in distinct cells forming the endosperm.

3. **Identifying Liquid Endosperm:** The question asks for the plant in which part of the endosperm is liquid. The coconut is known for having a liquid endosperm, commonly referred to as coconut water.

4. **Conclusion:** Among the options provided, coconut is the only plant where the endosperm has a liquid form. The coconut water represents the free nuclear endosperm, while the white kernel represents the cellular endosperm.

5. **Final Answer:** Therefore, the correct answer to the question is that the part of the endosperm is liquid in **coconut**.
